Using CURLOPT_TIMEOUT_MS correctly?

T'he behavior I'm experiencing from using this option (CURLOPT_CONNECTTIMEOUT_MS, also) is strange. Here is a code snippet: ---------------------- $c = curl_init("www.google.com"); curl_setopt($c, CURLOPT_RETURNTRANSFER, true); curl_setopt($c, CURLOPT_FOLLOWLOCATION, true); curl_setopt($c, CURLOPT_TIMEOUT_MS, 500); $resp = curl_exec($c); ---------------------- This ALWAYS returns an errno 28 (Timeout was reached) for ANY URL that I try. The only way I can get it to work is if I set the MS timeout value >= 1000. I can set it to 999 and it immediately fails, but bump it up to 1000 and everything is fine. Is anyone else seeing this behavior? ---------------------- My PHP- PHP 5.2.5 (cli) (built: Jan 24 2008 17:17:05) Copyright (c) 1997-2007 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies My cURL- curl 7.17.1 (i686-pc-linux-gnu) libcurl/7.17.1 OpenSSL/0.9.7e zlib/1.2.2 Protocols: tftp ftp telnet dict ldap http file https ftps Features: IPv6 Largefile NTLM SSL libz ---------------------- Thanks for any help you can provide. -Kevin
